I recently brought up 3 DomUs; the result, of course, is
that I now have 3
more machines to administer. This is known as a bad
tradeoff... I'm
curious, though, how other people are solving this.
My (NetBSD) DomUs are going to be mostly identical. I was
thinking of
having a shared, read-only /usr and separate /var. I
probably need
separate roots, if only to have separate /etc/rc.conf files.
/usr will be
a real partition, probably shared with the Dom0. The Dom0
would also have
a separate partition that held the vnds for the DomUs.
The problem is updating pkgsrc -- compilations on the Dom0
(with the DomUs
shut down) would be slow, since I'm not allocating much
phyiscal memory to
Dom0.
Anyway -- how are other people handling this? I thought
about NFS, but I
suspect it's too slow.
